Economic and Technical Analysis of Thick Coal Seam Mining Methods

Abstract:

Common mining methods for thick coal seams or extremely thick coal seams has slice mining top coal caving mining, greater height mining, and surface mining. From the perspective of economic and technological mining method, the choice of methods should be fully taken into account the technical, economic, quality of operating personnel, equipment, geological conditions. It allows priority to open-pit mining, and then according to the thickness, coal quality, coal other factors to select the top coal caving or mining of high extraction methods which can achieve the economic, security, and efficient purposes. Conversely, if the method is poor choice, it will certainly lead to economic and time losses.
